To all whom it ma@l Concern Be it lnovvii that I, ERNEST Menen, citizenof tlie United. States, anti a resident of the 'city of Chicago,countyvr of Coeli, anni Stute of illinois,- have invented certain newand useful Improvements in Couplings, of vvliieli tlie following is sspecification.

My invention relates to improvements in couplings, and more especiallyto couplings aclapied to serve as' ineonsvior aoiliteting the iniiationof automobile tires, and the like, the present invention being anirnprovenient on the invention set ortli in my prior application forCouplings, iled November lei, 1313, Serial No. 860,961.

The object of the invention is to provide zin improved ineens forpreventing undue iniizition of the tir. y

The invention eonsists in the combinations and arrangements of partshereinafter cleseribed and claimed,

The invention virili be leest understood by reference to theacoonipenring drawing forming part 'of this specification, and inWhich-- Figure l isl :i sitle vievv of a portion of an automobile Wheelequipped with e construetion embodying* my invention, Fig. 2, enenlirgecl vertical section taken through the valve nipple disclosed inFig. l, Fig. 3, a section token on line azzof Fig. f1, Fig. an enlargedsection token on line yfzj of Fig. 2, Fig'. 5, an enlarged detail Viewof a valve employed in the construction, and Fig. 6, :i sectioncorresponding to 2 out showing a sealing' oep employed in theconstruction in operative position.

The preferred forni of oonstruotion as illustrate@ in the 'drawinge'onpri'ses e perforated head l which is proviecl 'With o lireerleclsocket 2 adopted to iit over a threaded projection 3 on ich; ordinaryvalve nipple 4 :in ordinary v:roiintfi@bile tire, ee shown, n suitablesealing 1*'. er* being arranged in the bottom oi socket Z enel adaptedto facilitate the formation of an air tight joint. ring` 5 is svviveledon head l, saifl ring being helci iin `position thereon by means of asleeve 6 threaded-to the lower end 'of Suid head and aeo'ecl 'to enibmeevalve nipple #i to protect the seme enel sent an ornamental eppeez-fmee.sicle, ring 5 is provided with enr which is pivotecl. an arm or iin etits upper free encl a sealing cup 9. Seal desired to inilte Athe tire.

` is'pivotalijy connerie( WitA rpt-eri 'to y sai/cl ero f 20, seid linkl eii=g the other neteli ll adapted to imi/lor "lie eiresponding;r Y isition, hose hcoupling 14 may be readily arranged in operative relationwith head 1 and. valve ni'pple 4, and firmly secured in position bypassing link 19through one of the notches l1 and engaging the head 20under the corresponding shoulder of head 1 and passing the link 17through the other notch 11 and engaging clamping leverl on the otherside of said shoulder. Then, by throwing lever 18 downwardly, .coupling111 is drawn to a tight seat on head 1, so as to permit of the inrlationof the tire in the usual manner.

ln order to further seal and strengthen -the connection betweenncoupling 14 and head 1, a cap 22 is secured to the lower end ofcoupling 14 and is adapted to fit over the upper end of head l as shownin Fig. 2. A sleeve 23 is secured to the upper end of coupling 14 and isprovided With a Whistle opening 24 in one side so that the escape of airthrough said sleeve will sound the whistle and thus give an audible.signal. Sleeve 23 is connected with coupling li by a passage which isnormally olosed by valve 25 held normally in closed position by means eta compression spring 26. At its upper end spring 26 bears against thenose or' a threaded plug 2T and by means of which the tension of saidspring may be adjusted and consequently the pressure at which valve 25will open may be varied as, desired. Plug 2T is provided With anlindicator finger 28 cooperating with a dial 29 to indicate dili'ere'ntdegrees of pressure. Finger 28 and dial 29vare'inclosed by a cap 30having, a transparent Celluloid plate 31 at the top thereof so as topermit the inspection of dial 29 and finger 28. By this arrangement itwill be observed that spring 2G may be adjusted to cause valve 2.3 toopen at any desired pressure thus preventing injury to the tire byoverinliation. The specific arrangement will be found. to be a simpleand efficient one for the purpose.

Connected withthe cap 30 is a supplementary whistle 32 of smallercapacity than -thistle 22E- 2eL and provided with a whistle opening 33.Whistle 32 is connected with cap 30 through a minute opening 34 and aminute opening 35 is formed in plug 27 so as to permit the passageof airto cap 113.0

when valve 25 opens. such that when there is .too great an escape of airto operate Whistle 23-241, a portionl he arrangementy is modificationsas come with in the scopel of the f appended claims. y

Having described my invention what l claim as new and desire to secureby Letters Patent is:

1. The combination with a pneulnatie tire and a valve nipple forintl-ating the same, of a hose coupling seating upon said nipple; aspring held safety Valve in said coupling; a large Whistle arranged tobe operated by escape of air through said valve; a small supplementalWhistle havin@ a m nute connection with said large .vhif. g and meansfor clamping said couplingr to said nipple, substantially as described.

2. The combination with a ou' and a valve nippleior inflat of a. hosecoupling seating upon f an adjustable spring held said coupling; a largowhisile arranged to be operated by escape of air through said valve; asupplemental lWhistle having. a

'minute connection with said large iwhistle;

and means for clamping said coupling to said nipple, substantially asdescribed.

3. The combination With a pneumatic tire and a valve nipple forintlating the saine, ot'

a hose coupling seating upon said nipple; a

. safety valve in said coupling; a. perforated threaded plug arrangedopposite saixl valve; a spring seated on said plug and said -faire;

-a large Whistle arranged to be operated vby escape of' air through saidvalve; a small supplemental whistle arranged to be operated by airaassing through said perforated plug; and means for clamping saidwiupliug to said nipple, substantially .lcscribed.

In testimony whereof l have sig. al my name to this specification in thepresence ol two subscribing Witnesses.
